This is the conclusion I came to. 

I am not sure which is less painful. My gut says it would have to be added to a lot more places in gcc than newlib. It is easy to solve in newlib. Although it seems more correct to add it to GCC.

I suppose I should restart this thread over at GCC to get more opinions.

I am traveling this week. I reverted the warning fix patch locally if you want too revert it in the RTEMS tree.
